例句與造句

1. At the fundamental level, optical activity is a case of circular birefringence, and can best be understood in that way.
2. For instance, choosing right and left circular polarizations as basis functions simplifies the solution of problems involving circular birefringence ( optical activity ) or circular dichroism.
3. A combination of linear and circular birefringence will have as basis polarizations two orthogonal elliptical polarizations; the term " elliptical birefringence " however is rarely used.
4. Circular birefringence is also termed optical activity especially in chiral fluids, or Faraday rotation when due to the presence of a magnetic field along the direction of propagation.
5. Polarimetry can be used to measure various optical properties of a material, including linear birefringence, circular birefringence ( also known as optical rotation or optical rotary dispersion ), polarising filters, wave plates or other devices.
6. It's difficult to find circular birefringence in a sentence. 用circular birefringence造句挺難的
7. Whereas linear birefringence in a crystal involves a small difference in the phase velocity of light of two different linear polarizations, circular birefringence implies a small difference in the velocities between right and left-handed " circular polarization " s.
8. So we find that the degree of rotation depends on the color of the light ( the yellow sodium D line near 589 nm wavelength is commonly used for measurements ), and is directly proportional to the path length L through the substance and the amount of circular birefringence of the material \ Delta n which, for a solution, may be computed from the substance's specific rotation and its concentration in solution.
